The
-menuitems
option takes a list of lists describing
the menu items. For each menu item, an embedded anonymous list
describes the type of menu item, the label to use, and the
action to take when it is selected along with any other options
desired to configure the menu item. In this example, each
of the menu items is the
'command'
type, and we use the
-command
option for each item to point to the callback to execute when the
menu item is selected. We also use the
-underline
option to
enable the user to select a menu item using keystrokes.
(The
\[
quotedbl
]-"
represents a separator
between menu items.)
